The invention relates to the fixing of boards to a substructure using a connection piece (3, 13) which is arranged on a partial surface (1.1) projecting from the bottom of the longitudinal side surface of a board (1), and is connected to the substructure (2) by means of a fixing piece (4). The spring rate of the connection piece (3, 13) in relation to forces exerted on the contact surface with the board (1) is lower than that of the board on the contact surface. The elastic deformation region of the connection piece is larger than the region of the dimensional variations on the cross-sectional surface of the board, which appear as a result of the temperature and humidity variations occurring during normal use. |
